ultra destructible

Tamper seals using ultra destructible materials, typically PVC (vinyl) or acetate is one of the most basic and established techniques to ensure that a label cannot be removed and reapplied at all.

The technique works by using a very weak and brittle substrate and aggressive adhesive to ensure that the label disintegrates into many components if any attempt is made to remove it.

This is still a useful material for some applications, provided that the application does not require the label to exhibit any shear strength and the label and surface is not exposed to movement.

Used in combination with other printing techniques, this provides an economic way of sealing certain surfaces, provided that the presence of a permanent residue on the surface that is very difficult to remove is not an issue.
